Title: Production of active carbon having superior quality
Inventor: OTOWA TOSHIRO
IPC: C01B31/12
Filed: 1988-10-01
Abstract: PURPOSE:To obtain active carbon having a large surface area and extremely low S content by mixing coconut shell char as a carbon source with hydrous KOH as an activating agent in a specified weight ratio and treating the mixture by heating at a temp. suitable for activation. CONSTITUTION:Hydrous KOH particles having 2-25wt.% water content are charged at first in a reaction furnace, and melted by heating at their melting temp. (about 200-250 deg.C). Coconut shell char having a grain size ranging from those passing through a 100 mesh sieve and those remaining on the 100 mesh sieve are charged to the obtd. melt soln. and mixed. Suitable proportion of the coconut shell char to the hydrous KOH to be mixed is 1:2-1:6 by weight, pref. 1:3-1:5. The mixture is then heated at a temp. capable of causing activation of the coconut shell char, namely, at >=480 deg.C, particularly, 500-900 deg.C. A product is discharged from the reaction furnace after completing the heating, and washed and the dried. Thus, aimed active carbon having high quality and low S content is obtd.

Title: Vehicular auxiliary drive device
Inventor: TSUCHIYA KIYOSHI
IPC: B60L50/16
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a vehicular auxiliary drive device that enables appreciable starts on a hill and on a low-friction road. SOLUTION: A field-control motor 4 is connected to each rear wheel 3 that is not driven by the engine. Four switching elements Q1 to Q4 in H-bridge connection control a field coil 4a to regulate the direction of the moor revolution and the variation of the motor torque. A switching element Q5 is separately disposed to cause current to flow in an armature coil 4b. The motor field current is controlled so that it increases only for relatively low speed and remains low for relatively high speed. Appreciable control can be thus carried out depending on start conditions including starts on hills where high torque is necessary at low speed and those on low-friction roads where low torque is desirable at high speed.

Inventor: TSUBONE TOSHIAKI
IPC: C02F3/34
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To remove nitrogen in waste water by circulating a part of flow-out water from the downmost stream side reactor to the uppermost stream side reactor and making the upper most stream reactor into free from oxygen to keep a part of the generated NO2 -N in the oxygen free state in the prestage of the reactor thereby denitrificating the waste water by microorganism stuck to a carrier. SOLUTION: The reactor is divided into three stages and the flow-in waste 1 is charged to the 1st stage reactor 7 in the uppermost stream side, treated in the 2nd and 3rd stage reactor 8, 10, and discharged. A part of the discharged treated water 2 is circulated to the 1st stage reactor 7 through a circulating line 3.

In the 1st stage reactor 7, air is diffused by a coarse bubble generating device 6 and the carrier is stirred and fluidized. Since the diameter of the blown bubble is large, the oxygen is hardly dissolved into the reactor, and the reactor is kept in the oxygen free state sufficient to cause the denitrification.

Title: Light quantity controller
Inventor: USHIO YUKIHIDE
IPC: G03G15/04
Filed: 1988-10-04
Abstract: PURPOSE:To speedily raise light quantity to a desired one without irradiating a surface other than the picture area of a photosensitive medium with a laser beam by continuously boosting a driving current before a light emitting element begins to emit light and causing the light emitting element to emit light only in the area other than the photosensitive medium after the light emitting element begins to emit light. CONSTITUTION:The light quantity controller has a CPU 1, D/A converters 2 and 3, 1st and 2nd constant voltage circuits 4 and 6, a current switch circuit 7, a laser 8, an AND circuit 9, and a D-type flip flop 10. Before the light emitting element begins to emit light, the driving current is continuously boosted. Moreover, after the light emission of the light emitting element is detected, the element is caused to emit light only in the area other than the photosensitive medium to intermittently boost the driving current until a desired light quantity is obtained. Thus, a current light quantity can be speedily raised to a desired one without irradiating the surface other than the picture area of the photosensitive medium.

Title: Petroleum combustion device
Inventor: KAWASAKI YOSHITAKA
IPC: F23D3/10
Filed: 1984-11-28
Abstract: PURPOSE:To enable a large amount of radiation heat to be provided by a method wherein a red heated part of porous plates constituting a flat combustion chamber which faces against a window is constituted by a separate member which is separate from the other portions. CONSTITUTION:Fuel gasified from a wick 11 is mixed with air in a combustion chamber 17 which is flowed through small holes 15 and large holes 15' and burned with it. The red heat plate 16' having some large holes 15' closely formed thereto showsan excessive hot temperature under this combustion heat, resulting in making a red-heated condition. Therefore, a difference in temperature in the porous plate 16 and the red heat plate 16' becomes excessive and a large difference can be generated in both thermal expansions of both members. However, since the porous plate 16 and the red heat plate 16' are constituted by separate members, the circumference of the red heat plate 16' having a large thermal expansion volume is not fixed to the porous plate 16 having a low thermal expansion volume and the difference in thermal expansion is absorbed by the supporting grooves and the bending deformation of the plate is not produded. Therefore, an incomplete combustion caused by an irregular combustion and the dispersion in red heat in the red heat plate 16' are not produced.
